Leased lines advantages and disadvantages

Leased lines advantages and disadvantages

Business that use a leased line report many advantages to the system. Not least the dedicated nature of the service, that allows them to have unique access that doesn’t have to be shared with other customers. There are many ways that a business can facilitate digital communications between its staff, office locations, customers and other key audiences, including leased lines, broadband, ASDL connections or ASDL2. It is up to each individual business to research which system works best for their particular circumstances and requirements.

What is a leased line?

A leased line links two or more locations together via a dedicated, fixed bandwidth symmetric data connection. It might connect two offices from the same business or two data centres that regularly need to communicate with each other. Leased lines work using the same fibre optic business broadband technology that transmits light pulses down the cable; however, it can only be accessed by one, single customer.

Leased lines are commonly used by businesses that have a lot of data to transfer routinely, or that are concerned about the availability of a secure, dedicated communications line. The line can connect both PCs and servers to transmit data across multiple locations and telephones for secure, high-clarity voice calls.

Why does your business need a leased line?

Leased lines offer the customer a stable, high-quality fixed bandwidth connection that provides a digital communications system that goes beyond a normal business broadband package. The symmetrical nature ensures parity in the upload and download speeds, thus enabling the internet service to run smoothly and experience fewer glitches, due to the enhanced performance of the fixed bandwidth.

Your business is the only customer entitled to use the line, which enhances security when transmitting sensitive data or holding confidential phone calls. Additionally, the leased line allows more people to work remotely, e.g. from another office, hub, at home or during a business trip away from base. The service itself will also be more reliable, with predictable upload and download speeds, fully available bandwidth and dedicated maintenance support and advice, should things go wrong.

Leased line versus broadband: what’s the difference?

A leased line offers a dedicated, unified communications connection between your office or commercial premises and the local telephone exchange. You are the only user of your leased internet line and it provides fixed bandwidth and identical upload and download speeds. Business broadband is not quite so exclusive, as you will share the connection with other businesses in the area.

Several factors can affect the performance of business broadband that do not have any bearing on how a point to point leased line functions, including variable bandwidth, variances in upload and download speeds and contention with other users. There is also a difference in cost, with the dedicated nature of a leased line for businesses coming at a higher price.

Advantages of leased lines

Stable and faster speeds

There are, of course, many advantages and disadvantages to using a leased line, as there are with any business communications facility. A leased line will offer stable, faster speeds to enable your business to transfer data more quickly and reliably. This cuts down on delays and ‘gets the job done’ in less time.

Symmetrical service

The service is symmetrical, which means that you can predict the upload and download speeds, which do not alter, whatever time of day or night it is. You can plan precisely when you want to transfer data and don’t have to wait for period of time when fewer people are using the internet. This applies to larger files too, which can prove problematic when using other forms of internet connectivity.

Greater security protection

The service offers greater security against cyberattacks and data corruption. This enables people to work remotely with far greater confidence and handle sensitive phone calls with greater protection against hackers. The calls themselves are clearer too, thanks to the FTTC connectivity and enhanced connection to the exchange.

Staff can work remotely

Finally, more staff can work remotely, freeing up valuable office space and reducing overheads for larger premises. As more and more people discover the benefits of working from home or via a hotdesking system, this kind of business communications method will prove more and more popular and effective.

Disadvantages of leased lines


Of course, there are also downsides to using a leased business line. For a start, the cost is installing and subscribing to the line may be higher than other, comparable systems such as ADSL or broadband. Costs are slowly coming down, however, so it pays to shop around to find the best deal and most versatile providers.

Time it takes to Install

The installation of a leased line can take longer to complete too, sometimes up to three months. You will need to take more time to plan and schedule the project to ensure that your business communications can continue, uninterrupted. This is especially important to consider if you are moving to new premises or starting a new business and want to hit the ground running. Again, your provider, or a business communications expert can advise you on the most appropriate timescales.

Can be complex to understand

Finally, the system can be slightly more complex to get your head around than the alternatives. Make sure you read up on it carefully and ask your supplier or communications consultant about anything you don’t understand. Make sure you choose a leased line provider that offers after-sales customer support and technical back up services in with your overall leased line package.
